the pathologic basis on ouurence of cubitus varus is the collapse of medial humerus cortex caused by that the medial stress of fracture has been stronger than the lateral stress;the main reason for occurence of cubitus varus is the gravitational ulner deviation which has been caused by gravitational effect on distal end of fracture;The multilayer splintage is a elastic fixation system and a effective therapeutic method;The key to preventing cubitus varus is reasonable reduction and fixation and fixation and early exact x-ray appraisal.

结果：认为骨折的内侧应力较外侧强，使内侧骨皮质塌陷是产生肘内翻的病理基础：远折端受重力作用的重力性尺倾是产生肘内翻的主要原因；弹性固定系统的多层夹板固定，是有效的方法；预防肘内翻的关健是合理的复位与固定及早期正确的X线评价。
